Which of the following requires ATP A. facilitated diffusion
B. Simple diffusion
C. Active transport
D. None of the above​

Active transport

Explanation:

The process is considered "active" due to the use of ATP and actively requiring energy to transport molecules. Simple diffusion simply occurs through the membrane and facilitated diffusion uses transport proteins, but not ATP, hence why both are considered forms of "passive" transport.
